It is important to remember that if you delete a hierarchy before you take it out-of-service, the resource hierarchy will be removed from LifeKeeper protection, but the Apache instance will continue to run on the currently active server unless it is manually stopped or the system is rebooted. Attempting to recreate the same Apache hierarchy with a different IP address(s) or to create a new Apache hierarchy using the previously used IP address(s) (but using a different Server Root), will result in conflicts with the Apache instance that was left running with that same address.
To delete a resource hierarchy from all the servers in your LifeKeeper environment, complete the following steps:
- From the LifeKeeper GUI menu, select Edit, then Resource. From the drop down menu, select Delete Resource Hierarchy.
- Select the name of the TargetServer where you will be deleting your Web Server resource hierarchy. Click Next to proceed to the next dialog box.
Note: If you selected the Delete Resource task by right clicking from the right pane on an individual resource instance, or from the left pane on a global resource where the resource is on only one server, the Target Server dialog will not appear.
- Select the Hierarchy to Delete. (This dialog will not appear if you selected the Delete Resource task by right clicking on a resource instance in the left or right pane.) Remember that the list box displays every hierarchy on the target server , both in service and out of service. If you want to stop the Apache instance and remove the resource hierarchy from LifeKeeper protection, you must make sure that the hierarchy you choose is out-of-service before deleting it.
- An information box appears confirming your selection of the target server and the hierarchy you have selected to delete. Click Next.
- Another information box appears confirming that the Web Server resource was deleted successfully.
- Click Done to exit.
